Hammond HCM230UBK1 0U 23-Inch Flat Cable Manager Bar, 45° Offset

The HCM230UBK1 is a 23-inch wide horizontal cable management bar from the HCM Series, designed to support, route and provide strain relief for cable bundles behind rack-mounted equipment. It is a flat cable manager sold individually, aimed at IT, network, telecom, AV and broadcast installers who need rear cable support in 23-inch rack systems without giving up a full rack unit.

Construction is mild steel with a black textured powder coat finish. The finish is noted as GREENGUARD, TSCA and RoHS compliant, supporting indoor air quality and environmental compliance requirements, and the part is TAA-compliant and manufactured in North America for government procurement needs.

Overall dimensions are 0.62 in (16 mm) high, 23.00 in (584 mm) wide and 2.50 in (64 mm) deep, with a 45-degree offset (135-degree included angle) that creates standoff space between the cable bundle and the rack rails. The bar is pierced with 0.19 x 1.00 in cable tie slots for anchoring bundles, and a 4 foot roll of hook and loop fastener is included in the package. Shipping weight is 0.25 lbs (0.11 kg).

HCM230UBK1 mounts to EIA-310 mounting rails, so it can be positioned flexibly along the rack height and stacked vertically where larger cable volumes need support. Mounting hardware is not included. Typical placement is directly behind patch panels, switches and servers, where supporting cable weight helps maintain bend radius, reduce connector stress and keep airflow paths clear.
